Abstract
Binary CDMA는 음성 영상 등의 멀티미디어 데이터를 초고속으로 우수한 전송품질로 통신할 수 있는 우리나라가 개발한 새로운 표준 무선통신 기술이다. 본 논문에서는 전화선의 설치나 매설 작업 없이 원하는 장소에 자유롭게 설치할 수 있는 Binary CDMA 기반의 무선 VoIP 시스템 개발을 위한 개발방법 및 구현에 관해 연구하였다. Binary-CDMA VoIP 시스템의 구조를 설계하고, 호제어를 위한 메세지와 자료구조의 정의한 후, 사용자간 통화를 위한 착발신 단말 간의 호제어 메세지 흐름을 설계하고 구현하였다. Binary CDMA is a new standard technology for wireless communication developed by our country that makes high speed communications and good quality of services. In this paper we researched the development methods and implementation of a wireless VoIP System based on the Binary-CDMA technology that makes it freely installed in any place without phone cables and laying works. We designed the structure of the Binary-CDMA Wireless VoIP System and defined messages and data structures for call control. And then we designed and implemented call control message flow between VoIP terminals for user's communication.
